Craig Patterson, one of the greatest guys you will ever meet. Im sure most of us have been to one of his seminars or classes. He was in a little private canyon, few know about. Its called cardiff fork above donut falls in big cottonwood canyon. Myself and three others were up there sledding on tuesday, one of my best rides of the year. Craig was one of our greatest assets in the winter backcountry community. This is a huge loss for us!
